TEMPORARY BIIINDIEIR.A

To all whom 'it may concern: v v Be it known that I, IGEORGE P. WIGGIN- TON, a citizen of the Unit-ed States, residing at the city of Kalamazoo, county of Kala- Url mazoo, Stateof Michigan, have invented certain-new and useful Improvements in Temporary Binders, of which thefollowing is a specification. i

This invention relates to improvements 1n temporary binders.

The main objects 'of this invention are:

First, to provide in a temporary binder or loose sheetholder, an improved adjusting mechanism-` Second, t0 provide an improved binder or loose sheet holder of the binding core or `strip type Iin which the tensionon the binding strips is not materially varied by the opening or closing of the binder, or the 'swinging of the covers.

Third, to provide in a temporary binder, an

improved leaf clamping bar. Fourth, to

, provide an .improvedtemporary binder by 2&5. i ed that the covers may be made very thin."

, Fifth, to' provide an .improved bindingwhich any number of leaves up to' the maxi# mum may be effectively clamped and one in which the binder mechanism 1s so construct# mechanism which is particularly adapted for embodiment in light or small binders. Sixth, to provide in a temporary binder, an improved cover structure. Seventh, to provide an improved temporary binder which is very economical in structure and simple and easy to manipulate. 4 ,y

Further objects, and objects relating to structural details, will ldefinitely appear from the detailed description to follow.

I accomplish the objects of`my invention by the devices and means described in the following specification.

The invention is clearly defined and point- 'ed out in the claims.

i ture embodying 'the fe.-itures. of my inven,

A structure which is a preferred embodiy'ment of my invention is clearly illustrated `in the` accompanying drawing, forming a part of, this invention, in which:

Figure I is a .perspective view of a struction, the cover containingthe binding mechanism .being shown open, a portion of the other cover being broken away. Fig. II is a detail inside plan view of the structure shown in Fig. I, the leaves being shown in an upright position. Fig. III is an inverted r detail of the binder .adjusting mechanism.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the seetionalviews are taken looking in the direction of the little arrows at the ends of the section lines.y

Referring lto the drawing, the covers 1 and 2, in the embodiment of myl invention illustrated, are formed of boards, such as binders board, with an outer covering 3 of leather. At the inner ends ofthe boards are cover 'bars 4 formed of sheet metal folded longitudinally upon the ends of the cover boards. The coverb'oard of the cover 2 is cut away at its inner end to provide a cover j recess 5. The folded edges of the cover bars 4 are curved to provide bearing knuckles 6 yfor the leaf clamping bars 7. Theseleaf clamping bars'are in the form of flat strips of metal, and are disposed in bearing engagement with the vknuckles of the cover bars 4..

The clamping bars are provided with rearwardly projecting loop-like pintle members or knuckles 8, which project into openings 9 provided therefor in the cover bar knuckles. These knuckle openings are deep enough to permit the leaf clamping bars to swing` against either side of the cover bars The pintles 1 0 are arranged in the cover bars 4 to engage the clamping bar knuckles. The'binding strips 11- are arrangedthrough openings l12 provided therefor in the cover bars, and throughalined openings 13 in the The openings '12 in the cover bars are deep enough so thatv the binding strips swing freely therein, no matter what position the clam assume relative to the covers.

The binding strips are secured tof-the cover bar ofthe cover lby means of-the' ping bars to es 14, which are formed integrally witl its cover bar, the tongues being V- when suiiicient stress is applied to the binding str1 they are eectivel sup orted so that alliough ythe barsare crm of light sheet metal and the tongues made comparatively small, they are still capable, when thus positioned of sustaining very heavy strains. The binding strips are adjustably secured to the other cover b means of the ratchet bar 17, on which is 4slidably mounted the'bar-like bind' stri adjusting member 18. A pawl 19 is p1vot at 20 on the under side' of the member 18 to coact with the rack bar.v4 The outer end of the pawl 19 islextended laterally and turned up tofprovide a er piece 21. lThis finger piece engaging e of the bar serves as -a stop for the awl. 1n one direction. A stop 22 is provided for limiting its movement in the other direction. When the finger piece engages the edge of the member 18, the pawl 1s 1n its engaging position, and when it is l 'at the stop^2'2,it is in its disengaging posiand pull t tion.

A U-shaped spring 23 is mounted on the,

stud 24-by one of. its arms, the other arm engaging the end of the pawl so that the spring serves to yieldingly hold'the pawl ineit er position..

.The bar 17 is arranged in the cover recess 5', it being supported. by the armor plate 25 on the cover bar, which is disposed at the rear of the recess with its inner end connected tothe cover bar. The' bar support 25 is govided with bar engaging tongues 28.l the structure illustrated, the arm nis formed integrally with the bar. (See Fig. IV.) 1 i f The recess 5 `is open member V18 may be asped for manipulation that is,"the binder is tightened by graspin the member 18 and pulling the same ou wardlyl The pawl being adjusted to its engaging position, retains the member 18 in its adjusted position. To release the" bind' mechanism, it is only necessary to shift t e Rawl to its disengralging position e covers apart. e pawl 19 is p-ovided with finger holds 27 on its front 4 n the moditied structure shown in Figs. IX and X, the member 18 is slotted 4at29 and the Vpawl 19`lis provided with a stud-like finger pxiece 30, arranged in the slot. Inv this formgegtme ends ofthe slot are the stops for the pawl. ratchet adjustment mechanism is a modieation and adaptation of the so'that theadjiisting.

'cover bar knuckles and ratchet adjusting mechanismshown in the patent to Harry F. Bushong, dated Feb. 4, 1908, )Td-878,340, and it is one of the objects of my present invention to simpli that mechanism and adapt it for light blnders, or holders of the type here illustrated, in which the covers are thin and light, and the structure issimple and economical.

By arranging the clamping bars and their coacting members on the cover, as illustrated, I secure a binder in which the covers may be opened to their ullest extent, or

manipulated, as desired, without varying the tension on the binding cords. This is of very great advantage in that the covers remain in their adjusted positions; that is,

extended in the flat, as shown in Fig. II or closed or may be swung back to back as shown in Fig. VII, witl` no tendency to assume some other position. Further, by maintaining this constant tension, the binding strips are not unduly strained or stretched, as may be the case where the tension is varied by the manipulation of the covers.

My. improved binder is very simple and economical," quickly adjusted, and as stated, is very compact and light in weight, so that my improvements may be embodied in light binders such as order holders or the like.

I haveillustrated and described my improvements in detail .in the form in which Ihave embodiedthem. While I am aware I that various modifications and structural details are possible, I have not attempted to illustrate or describe such modifications herein, as they will be readily understood by those skilled in the art to which this invention relates.
